Quoted message said:Fellow Cyclists,
I had a professional fitting done to in anticipation of ordering a
custom geometry bike. With the fitting I found out that I had a short
torso and arms which requires a geometry with a high front end and
relatively shorter top tube. The fitting was done on a Serotta Size
Cycle but the frame was done by another manufacturer.The frame builder addressed these issues with a longer seat tube and a
slightly sloping (up) top tube and a taller head tube. Unfortunately
in dealing with these issues it appears that the stand over height was
missed by about 3/4" i.e. the bike is about 3/4" higher than was
recommended by the fitting.So far I have had a test fitting on the new bike but haven't been able
to ride it since the seat post provided was too long (won't go low
enough). I can just barely straddle the bar with bike shoes on. I
would estimate that there is currently somewhere 0-1/4" clearance if I
stand just right. The bike currently has 23mm tires on it but I will
probably switch to 25mm when these wear out to reduce the chance for
flats. This will only make the stand over height worse.Is this stand over height likely to be an issue? At what point would
you consider stand over height to be insufficient?Thanks,
Steve
You don't actually need *any* standover height to ride a road bike on the
road, but a little is usually considered desirable by most people. If you
can straddle it with both feet on the ground, you've got enough. When you
say the builder missed it by 3/4 of an inch, that's implying a precision
formula in these matters which really does not exist. Any custom frame is
going to compromise something in order to achieve something else, otherwise,
you could just get a standard production frame. I have a custom-built
made-to-measure frame, and, with 25mm tires on it, I can just straddle it in
bare feet, and with my riding shoes on, I have about an inch of clearance,
which I think is ideal. If you're concerned a mistake was made, ask the guy
who is responsible for designing your frame.
